Application filed December 0, 1980. Serial No. 152,854.

This invention appertains to spectacle frames and it has particularreference to means for reinforcing the nose-bridge and temple-bars ofsuch frames.

One object of the invention is to provide an improved method ofreinforcing an ophthalmic mounting. which shall be superior to the slowand tedious,-inconven1ent as well as inaccurate steps hitherto employedin strengthening the bridge and temple pieces of spectacle frames.

Another object is to roduce a reinforcement of the nature set orth,capable of being expeditiously and advantageously incorporated in anophthalmic mounting during its process of manufacture.

A further object is the production of a 'means of the type specifiedparticularly.

adapted to reinforce nose-brid es and temple-bars of spectacle frames mae of genuine and imitation tortoise-shell or analogous substances, stillleaving the mottled or streaky markings occurring in the latterundisturbed.

A still further object is to furnish a re inforcement of the speciesmentioned, appli cable to ophthalmic mountings, without the necessity ofdrilling or forcing a hole through the same by means of a heated wire.

A still further object consists in roviding a reinforcement of the kindre erred to,

- which when secured within the members of an ophthalmic mounting, notonly permits of the same being bent to conform to the contours of thewearers head, but that will also serve to retain the conjoinedreinforcements and members in the various shapes imparted thereto.

An additional object is to supply a reinforcement of the classalludedto, composed of a minimum of simple parts, readily placed in theirassigned positions, besides amenable to low cost of manufact re.

Other objects and advantages of the invention will becomeapparent as thespecification proceeds.

With the aforesaid objects in view, the invention consists of the novelcombinations and arrangements of scribed in their pre erred embodiments,pointed out in the subjoined claims, and illustrated on the annexeddrawing, wherein like parts are designated by the same referencecharacters throughout the several views.

arts hereinafter de-.

Briefly described, the invention under consideration includes in itsorganization a piece of wire of approved material, size and length,constituting the proper. This wire is lodged upon the bottom of a grooveor channel of greater depth than the thickness of the reinforcement,itself, and cutv longitudinally of the roughened-out nose-bridge andtemple-bars ertaining to 'the blank of an ophthal inic mounting made ofreal or artificial tortoise shell. A sealing strip preferably composedof a like substance to the aforesaid nose and temple parts, is securedby means of a suitable cement in the groove over the wire. The stripspoken of, fills the groove completely, retaining the before namedreinorcement in place therein. The finishing operation performed on theframe in ques tion, removes surplus or projecting portions of thesealing strip, making the same flush with the exterior surfaces of theparts referred to. The latter can be bent or offset to fit the nose andside of the wearers head, the reinforcements within the bridge andtemple parts mentioned, keeping them in the shapes imparted thereto.

The advantages of the invention as here outlined are best realized whenall of its features and instrumentalities are combined in the one andsame structure, but, useful devices may be produced embodying less thanthe whole.

It will be obvious to those skilled in the art to which the inventionappertains, upon becoming conversant with the detailsthereof, that thesame may be incorporated in several different constructions. 'Theaccompanying drawing, therefore, is submitted merely as showing thepreferred exemplification of the invention.

In the said drawing:

Fi re I is a front view of a blank from whic the lens frames of anophthalmic mounting is made, the manner of reinforcinthe nose bridgethereof being shown;

ig. II is a section taken on the line IIII of Fig. I, looking in thedirection pointed out by the arrows;

Fig. III is a fragmentary section and edge view of an ophthalmicmounting, illustrating particularly the reinforcement of the bridgeieceand one of the temple-bars;

Fig. V is an enlarged section on the lines reinforcement Ill IV-IV ofFigs. I and III, looking in the direction of the thereto appertainingarrows; and

Fig. V is also a front-view of the lens frames, corresponding to Fig. I,representing the same in completed condition.

Referring now to these several views for a detailed description of theinvention thereby exemplified in one of its preferred embodiments, itwill be observed that the known parts of an ophthalmic mountingwherewith this reinforcement is associated and coacts have beendesignated by letters of reference, instead of numerals as are used todenote the present improvement. This was done it will be understood,merely to intimate that the said parts are not treated or considered aspertaining exclusively to the latter but are claimed herein only so faras they form therewith legitimate eombinations of elements capable ofyielding novel and useful results.

Of these reference letters, A identifies a roughened out blank fromwhich the lens frames of an ophthalmic mounting is formed. A blank ofthis character may be composed of either genuine or imitation tortoiseshell, such as any of the ordinary celluloid compositions. The blank Acomprises spaced apart lobes B conjoined by a connecting piece C andhaving lugs D projecting outwardly beyond the lobes oppositely to saidconnecting plece. Out of the lobes B arecut the lens rings or rimmembers 13 (Fig. V), havin the usual internally bevelled lens seats BFig. HI). From the connecting piece C is formed the nose-bridge C thelugs D when dressed down to their proper size, constituting the ears Dto which hinges E for temple bars F are secured, as is common practice.

In order to introduce the reinforcement where required in thenose-bridge, the blank A is first clamped down flatwise on a suitablemachine table, and then a groove or channel 11 is milled for a certaindepth, in a longitudinal direction through the middle of the connectingpiece C This groove extends preferably into the solid portions of thelobes B, far enough to afford a straight or level hearing or seat in thebottom thereof for a reinforcing element 13, to rest on. The latter mayconsist of any suitable material, but by preference a low carbon steelwire is used therefor. Notwithstanding that a reinforcing element ofsquare section has been indicated in Fig. VT, it will of course beunderstood that a wire of any other approved configuration may beemployed in its stead. The thickness of the reinforcing element isselected normally to be about half the depth of the groove 11, while inwidth it fills the latter. The aforesaid element 13 is of a lengthsomewhat shorter than the distance between the adjacent inner faces ofthe rims 13', so that there will be no danger of the ends of the wirecoming into contact with the edges of the glass lenses to cause injuryor possible fracture of the same.

With the object of retaining the wire element in its assigned position,a sealing strip 15 is lodged in the groove 1 over and upon the wiretherein. The seal referred to, is to a certain extent, made longer thantne wire 13 which it completely covers. At such times as the lobes B arehollowed out to produce the rim rings B those portions of the strip 15which project within the channels 11., beyond the inside margins of thesaid lens frames, indicated by dot-and-dash lines I) in Fig. I, are alsocut away. It does not make any difference that a small interstice isleft at each end of the groove in question, i. e. between the interiorface of the lens seats and the terminals of the reinforcing wire. As ageneral rule, cement of a suitable kind is employed in thereinforcen'lent receiving channel, both to imbed the wire element 13therein, and for causing the sealing strip 15 to adhere to the sides ofthe said groove 11. For the strip mentioned, the same material of whichthe blank A consists, can be used, or if desired, some other substance,of a different color,

may be substituted, in order to obtain a variant effect. It will be seenthat by virtue of the groove 11 cut into the side of thelobe-connecting-bridge B, the wire element 13 is not surrounded entirelyby this bridge, the strip 15 being a separate sealing and fillingmedium. At 17 is indicated a thin covering preferably composed of thesame material as the mounting, being cemented over the sealing strip tothe same side of the nose-bridge C The covering referred to, serves asan additional safe-guard to hold the sealing strip 15 from coming out ofthe groove 11, and also to prevent the latter from opening up when thebridge is subjected to bending or twisting stresses.

For the temple bars, one whereof is shown at F, Fig. HT, the same methodis followed in strengthening these as in reinforcing the nose-bridge. Achannel 11 is grooved in the side of the said bar F, while the same isin the flat or straight condition, depicted by dot and dash lines at 7.The odset F occurring at the free end of the aforementioned bar, can beformed therewith, either before or after the reinforcing element 13 andthe sealing strip 15 are placed in their assigned positions. Obviously,if the end of the temple-bar is set-01f as at F before lodging the wireand seal in place, the last named parts must also be made to conform inadvance to the shape imparted to the said bar. It stands to reason thatif needed, coverings like 17, can be applied to the sides areincorporated with the nose-brid e and temple-bars, the same may be benturther by the optometrist, fitting a particular formation of human headto which the ophthalmic mounting is to be applied. The wire element inquestion will always tend to retain the bridge and temple members in theshape they were last given. It is also clear, that with proper fixtures,a groove or channel like those illustrated, namely 1111, can be cut inthe bridge B and bars F, more accurately and. expeditiously, than itwould take a small and delicate drill or heated wire to pierce thru alike distance of material. Insertion of the reinforcing element 13, andcementing of the thereover superimposed sealing strip 15, can readily beperformed by less costly and, skilled labor than what would be requiredfor either drilling or burning. Such portions of the sealing strip whichproject beyond the outermost edges of the reinforcement receivingchannel can quickly be dressed off.

Wh1le a certain preferred embodiment of this device has been shown anddescribed, it will-be understood that changes in the form, arrangements,proportions, sizes and details thereof may be made, without departingfrom the scope of the invention as defined by the ap ended claims.

Having descri ed my invention what I desire to secure by Letters Patentand claim,
